This talk presents results of the two independent analyses evaluating the measurement accuracy of the branching ratio for the Standard model Higgs boson decay to a W-pair, at the Compact Linear Collider (CLIC) and at the International Linear Collider (ILC). The considered Higgs production channels are the WW-fusion for the highest energy stage of CLIC, √(s)= 3 TeV, and the Higgsstrahlung process for the nominal ILC energy, √(s)=500 GeV. Both studies are performed using the full simulation of the detector. The realistic experimental conditions have been simulated including beam energy spectrum, initial state radiation and the backround from γγ→ hadrons processes, which are overlaid on simulated events. The multivariate analysis technique is used for the final event selection and the expected relative statistical uncertainty, Δ(σ⋅ BR) / (σ⋅ BR), of the measured Higgs production cross sections is estimated.
